Hello everybody!
I'm working on a tube. In my work I'm using a Fortran subroutine that is compiled to CFX (User CEL). I need to get access to the elements coordinates or Element-to-vertex Connectivity in the inlet of a tube. Based on CFX documentation it is possible by calling "USER_GET_MESHDATA" subroutine. However, I think first I need to call "USER_GET_MESH_INFO" subroutine to obtain the values of integer variables defining these arrays, is not it? I'm just starting with CFD. Could you help me?

Before going too deep into the FORTRAN jungle, tell us why you need the coordinates at the inlet face? Do you want to prescribe inlet flow profiles?

I'm sorry, I'm just starting with Fortran in CFX. I want to deform the grid in the process of solving. I want to use something like this:
(x, y, z) - mesh coordinates.
(xx, yy, zz) = (x, y, z) + (u(x, y, z), v(x, y, z), w(x, y, z))

Is there a reason you cannot use the built in mesh deformation functions? Have a look at Specified displacement
